I don't know where you got those numbers from. Momentum of an object is equal to mass times velocity. Change in momentum is equal to impulse, which is force times time. Therefore f * t = mv, and change in v = f * t / m. Plugging in the numbers, (0.00005 N) * (3600s/hour * 24 hours * 365 days) / (722 kg) = 2.18 m/s
